Caution The above connection diagram and constant will not guarantee successful operation. Perform

thorough evaluation including the temperature characteristics with an actual application to set the

constant.

 Condition of Application

Input capacitor (C_IN):

Output capacitor (C_L):

A ceramic capacitor with capacitance of 1.0 μF or more is recommended.

Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external

parts. Perform thorough evaluation including the temperature characteristics with an actual

application using the above capacitors to confirm no oscillation occurs.

 Selection of Input Capacitor (C_IN) and Output Capacitor (C_L)

The S-1324 Series requires C_Lbetween the VOUT pin and the VSS pin for phase compensation. The operation is

stabilized by a ceramic capacitor with capacitance of 1.0 μF or more. When using an OS capacitor, a tantalum capacitor

or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF or more. However, an oscillation may occur

depending on the equivalent series resistance (ESR).

Moreover, the S-1324 Series requires C_INbetween the VIN pin and the VSS pin for a stable operation.

Generally, an oscillation may occur when a voltage regulator is used under the conditon that the impedance of the power

supply is high.

Note that the output voltage transient characteristics vary depending on the capacitance of C_INand C_Land the value of

ESR.

Caution Perform thorough evaluation including the temperature characteristics with an actual application to

select C_INand C_L.

 Operation

1. Basic operation

Figure 16 shows the block diagram of the S-1324 Series to describe the basic operation.

The error amplifier output voltage (V_error) is divided by the feedback resistors (R_sand R_f). In order to keep the

feedback voltage (V_fb) equal to the reference voltage (V_ref), the error amplifier outputs V_error. The preamplifier controls

the output transistor to keep V_errorequal to the output voltage (V_OUT), and consequently, the regulator starts the

operation that holds V_OUTconstant without the influence of the input voltage (V_IN).

2. Output transistor

In the S-1324 Series, a low on-resistance P-channel MOS FET is used between the VIN pin and the VOUT pin as the

output transistor. In order to hold V_OUTconstant, the on-resistance of the output transistor varies appropriately

according to the output current (I_OUT).

Caution Since a parasitic diode exists between the VIN pin and the VOUT pin due to the structure of the

transistor, the IC may be damaged by a reverse current if V_OUTbecomes higher than V_IN.

Therefore, be sure that V_OUTdoes not exceed V_IN+ 0.3 V.

3. ON / OFF pin

The ON / OFF pin controls the internal circuit and the output transistor in order to start and stop the regulator. When

the ON / OFF pin is set to OFF, the internal circuit stops operating and the output transistor between the VIN pin and

the VOUT pin is turned off, reducing current consumption significantly.

The internal equivalent circuit related to the ON / OFF pin is configured as shown in Figure 17 and Figure 18. Note

that the current consumption increases when a voltage of V_SLmax.^*1to V_IN− 0.3 V is applied to the ON / OFF pin.

3. 1 S-1324 Series A / C type

The ON / OFF pin is internally pulled down to the VSS pin in the floating status, so the VOUT pin is pulled down

to V_SS

.

3. 2 S-1324 Series B / D type

The ON / OFF pin is not internally pulled down to the VSS pin, so do not use it in the floating status. When not

using the ON / OFF pin, connect it to the VIN pin.

(refer to Figure 17).

4. Discharge shunt function (S-1324 Series A / B type)

The S-1324 Series A / B type has a built-in discharge shunt circuit to discharge the output capacitance.

The output capacitance is discharged as follows so that the VOUT pin reaches the V_SSlevel.

(1) The ON / OFF pin is set to OFF level.

(2) The output transistor is turned off.

(3) The discharge shunt circuit is turned on.

(4) The output capacitor discharges.

Since the S-1324 Series C / D type does not have a discharge shunt circuit, the VOUT pin is set to V_SSlevel through

constant current load between the VOUT pin and the VSS pin. The S-1324 Series A / B type allows the VOUT pin to

reach the V_SSlevel rapidly due to the discharge shunt circuit.

6. Overcurrent protection circuit

The S-1324 Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor. When

the VOUT pin is shorted with the VSS pin, that is, at the time of the output short-circuit, the output current is limited to

50 mA typ. due to the overcurrent protection circuit operation. The S-1324 Series restarts regulating when the output

transistor is released from the overcurrent status.

Caution This overcurrent protection circuit does not work as for thermal protection. For example, when the

output transistor keeps the overcurrent status long at the time of output short-circuit or due to other

reasons, pay attention to the conditions of the input voltage and the load current so as not to

exceed the power dissipation.

7. Thermal shutdown circuit

The S-1324 Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature

increases to 150°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped.

When the junction temperature decreases to 120°C typ., the thermal shutdown circuit becomes the release status,

and the regulator is restarted.

If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and V_OUT

decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal shutdown

circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted, thus the

self-heating is generated again. Repeating this procedure makes the waveform of V_OUTinto a pulse-like form. This

phenomenon continues unless decreasing either or both of the input voltage and the output current in order to reduce

the internal power consumption, or decreasing the ambient temperature. Note that the product may suffer physical

damage such as deterioration if the above phenomenon occurs continuously.

Caution 1. When the heat radiation of the application is not in a good condition, the self-heating cannot be

limited immediately, and the IC may suffer physical damage. Perform thorough evaluation

including the temperature characteristics with an actual application to confirm no problems

happen.

2. If a large load current flows during the restart process of regulating after the thermal shutdown

circuit changes to the release status from the detection status, the thermal shutdown circuit

becomes the detection status again due to self-heating, and a problem may happen in the restart

of regulating. A large load current, for example, occurs when charging to the C_Lwhose

capacitance is large.

Perform thorough evaluation including the temperature characteristics with an actual application

to select C_L.

 Precautions

• Generally, when a voltage regulator is used under the condition that the load current value is small (10 μA or less), the

output voltage may increase due to the leakage current of an output transistor.

• Generally, when a voltage regulator is used under the condition that the temperature is high, the output voltage may

increase due to the leakage current of an output transistor.

• Generally, when the ON / OFF pin is used under the condition of OFF, the output voltage may increase due to the

leakage current of an output transistor.

• Generally, when a voltage regulator is used under the condition that the impedance of the power supply is high, an

oscillation may occur. Perform thorough evaluation including the temperature characteristics with an actual application

to select C_IN.

• Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external parts. The

following use conditions are recommended in the S-1324 Series, however, perform thorough evaluation including the

temperature characteristics with an actual application to select C_INand C_L.

Input capacitor (C_IN):

A ceramic capacitor with capacitance of 1.0 μF or more is recommended.

Output capacitor (C_L): A ceramic capacitor with capacitance of 1.0 μF or more is recommended.

• Generally, in a voltage regulator, the values of an overshoot and an undershoot in the output voltage vary depending

on the variation factors of input voltage start-up, input voltage fluctuation and load fluctuation etc., or the capacitance of

C_INor C_Land the value of the equivalent series resistance (ESR), which may cause a problem to the stable operation.

Perform thorough evaluation including the temperature characteristics with an actual application to select C_INand C_L.

• Generally, in a voltage regulator, an overshoot may occur in the output voltage momentarily if the input voltage steeply

changes when the input voltage is started up, the soft-start operation is performed, the input voltage fluctuates etc.

Perform thorough evaluation including the temperature characteristics with an actual application to confirm no

problems happen.

• Generally, in a voltage regulator, if the VOUT pin is steeply shorted with GND, a negative voltage exceeding the

absolute maximum ratings may occur in the VOUT pin due to resonance phenomenon of the inductance and the

capacitance including C_Lon the application. The resonance phenomenon is expected to be weakened by inserting a

series resistor into the resonance path, and the negative voltage is expected to be limited by inserting a protection

diode between the VOUT pin and the VSS pin.

• If the input voltage is started up steeply under the condition that the capacitance of C_Lis large, the thermal shutdown

circuit may be in the detection status by self-heating due to the charge current to C_L.

• Make sure of the conditions for the input voltage, output voltage and the load current so that the internal loss does not

exceed the power dissipation.

• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic

protection circuit.

• When considering the output current value that the IC is able to output, make sure of the output current value specified

in Table 12 in " Electrical Characteristics" and footnote *5 of the table.

• Wiring patterns on the application related to the VIN pin, the VOUT pin and the VSS pin should be designed so that the

impedance is low. When mounting C_INbetween the VIN pin and the VSS pin and C_Lbetween the VOUT pin and the

VSS pin, connect the capacitors as close as possible to the respective destination pins of the IC.

• In the package equipped with heat sink of backside, mount the heat sink firmly. Since the heat radiation differs

according to the condition of the application, perform thorough evaluation with an actual application to confirm no

problems happen.

• ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products

including this IC of patents owned by a third party.
